Fan cylindrical foundation composed of secant piles and construction method
The invention relates to a fan cylindrical foundation composed of secant piles and a construction method. The fan cylindrical foundation comprises a reinforced concrete bearing platform and the secant piles, the reinforced concrete bearing platform is connected with a fan tower tube, the secant piles are embedded into the bottom surface of the reinforced concrete bearing platform and connected into a whole, the secant piles are in a circular tube shape, reinforced concrete guide walls playing a role in guiding and fixing during construction are arranged on the inner sides and the outer sides of the secant piles, the secant piles comprises a plurality of unit piles evenly arranged along the circumference, and the adjacent unit piles are meshed with each other. Compared with the prior art, the problem that undisturbed soil is damaged during heavy excavation or open caisson construction can be avoided, and compared with a conventional pile foundation, the construction period is short, and economical efficiency is good.
本发明涉及一种由咬合桩组成的风机筒形基础及施工方法，所述风机筒形基础包括钢筋混凝土承台和咬合桩，所述钢筋混凝土承台与风机塔筒连接，所述咬合桩嵌入钢筋混凝土承台的底面，连接为整体，所述咬合桩呈圆形筒状，内外侧设有在施工时起到导向和固定作用的钢筋混凝土导墙，所述咬合桩包括沿着圆周均匀布置的若干单元桩，相邻单元桩相互咬合。与现有技术相比，本发明不仅可以避免大开挖、或沉井施工时破坏原状土的问题，而且相比常规的桩基础工期短、经济性良好。
